UV filters are the commonest filters bought with each lens buy. You will have in all probability heard {that a} UV lens filter protects your lens from getting scratched. It’s definitely true, however are you aware how to decide on the greatest filter to guard your digicam lens?
The perfect filter to guard your digicam lens known as UV Safety Filter (Ultraviolet Filter). The standard UV filters defend your costly lens from bodily injury (scratches, bumps) and have minimal or no impact on picture high quality.
What Is а UV Filter?
Initially UV filters (Ultraviolet Filter) have been developed in movie pictures days. A UV filter was obligatory because the filters blocked undesirable ultraviolet mild from hitting the movie. The picture suffered haziness and fogginess and not using a UV filter, particularly in blue hues.
Since fashionable digital cameras have built-in UV filters on the sensor degree, the necessity for UV filters is minimal at the moment.
It’s a widespread perception that UV filters cut back chromatic aberration or coloration fringing, however I’ve by no means seen any proof of that with my eyes. Based mostly on my expertise, if a lens is poorly constructed, no filter can right the colour fringing it produces. And if UV filters do cut back chromatic aberration, the discount is just too insignificant to make a distinction in picture high quality.
In the present day, the one perform that UV filters provide is safety. There’s little or no distinction between clear or UV safety filters.
Utilizing UV Safety Filter in Trendy Pictures
That is typically a subject of debate within the pictures neighborhood as a result of there isn’t any clear consensus about utilizing UV filters for cover functions in digital pictures.
Totally different photographers method UV protecting filters in a different way.
We are able to separate most photographers into three teams relying on how they use UV filters.
- Group 1. Some photographers by no means use protecting or UV filters as a result of they imagine that including an additional layer of glass in entrance of an costly, state-of-the-art lens can probably degrade the standard of the picture. We name these photographers “the perfectionists.”
- Group 2. Photographers within the second group use UV protecting filters solely when obligatory. For instance, if you happen to attend the Burning Man pageant within the desert, you’ll sometimes clear the entrance ingredient of your lens round 100 occasions every day. The sand and mud can probably injury your lens.
- Group 3. The ultimate group of photographers is those that instantly connect a UV safety filter after they buy a lens and by no means take away it. The logic right here is that the chance of damaging the lens far outweighs the minimal degradation within the high quality of pictures and, in consequence, is value it in the long term.
How I Use UV Safety Filters
For a very long time, I belonged to the primary group of “perfectionists” and refused to make use of the protecting filter. I believed utilizing the lens hood was higher to guard my lens from any potential bodily injury.
What modified my thoughts was my frequent travels to the West Coast of the US. As a result of robust winds alongside the coast, saltwater mist is at all times current within the air, even when it’s not raining. Continually wiping the entrance ingredient of any lens can simply trigger injury to its coating, particularly when salt residue is current.
At this level, I’ve UV safety filters for all my lenses, however they largely keep in my bag. I solely use them when obligatory. Earlier than mountain climbing alongside the coast, I at all times connect the filters to my lenses the evening earlier than. And earlier than driving via Dying Valley, I additionally guarantee all my lenses are protected with filters.
What are the negatives of utilizing UV Safety Filters?
To reply the query in regards to the damaging unintended effects of utilizing protecting UV filters, we have to perceive the properties of glass in optics. They’re mild transmission and lightweight reflection. They point out the ratio of sunshine that comes via glass versus the sunshine mirrored by the glass.
As a common rule, the optical flat glass transmits 95% of sunshine, and 5% is mirrored.
It signifies that if you happen to shoot via the optical glass, you lose 5% of sunshine and are at the next danger of undesirable lighting results similar to lens flare and ghosting.
In sensible phrases, it’s best to use UV protecting filters with the highest transmission and the bottom degree of reflection.
What to Search for When Buying Protecting UV Filters
Filter Materials
You in all probability observed that you would purchase a UV filter for as little as $2-3. The rationale for that’s they’re manufactured from plastic. The reflection fee of plastic is way larger than even common glass and may be larger than 15%. Keep away from plastic filters.
Even if you happen to discover a low-cost ($10-15) UV filter manufactured from glass, it’s virtually assured it’s not manufactured from optical glass. It’s extremely possible made out of low-coast development glass.
It will be greatest to search for UV safety filters manufactured from optical glass. And to maximise the safety degree of your lens, the filter must be geared up with tempered glass.
Nanocoating vs Multicoating vs Non-Coated Filters
As I discussed above, even high-quality optical glass may have a mirrored image fee of round 5% or larger. To scale back the reflection, filter producers use numerous kinds of coating.
Proper now, yow will discover three primary kinds of filter coating.
Non-Coated Filters
Such a coating is easy; it merely doesn’t exist. If the filter is supplied with high-quality optical glass, you’re going to get a mirrored image fee of about 5%. With a non-coated filter, will probably be extra affected by lens flares and ghosting.
Multicoating Filters
Many of the medium and high-quality filters at the moment use multicoating. The mix of high quality optical glass and multicoating can cut back the reflection fee by as much as 1%.
Nanocoating Filter
Nanocoating is the late know-how used to scale back and even eradicate the reflection fee for good. You’ll find new nanocoating know-how in some costly high-end filters.
Counterfeit UV Filters
Watch out the place you purchase protecting filters. When you discover a high-end filter at a fraction of the retail price, it’s assured to be a counterfeit from China. Be sure to purchase your optics from respected retailers. Keep away from eBay and AliExpress, the place most counterfeit optics are bought.
How A lot Ought to You Spend On Protecting UV Filters
The straightforward reply is as a lot as potential to buy a UV Safety Filter with high-quality tempered glass with multicoating or multicoating.
On the identical time, shopping for a $100 UV Filter to guard a $150 equipment lens wouldn’t be sensible. As a result of cheap lenses are usually not constructed utilizing the best high quality glass and coating, the lens’s mild transmission is already low. The costly protecting UV filter received’t be capable to right lens flaws and imperfections.
Fortunately for us, there’s a easy rule of thumb in pictures. It states that, on common, you have to spend on a UV safety filter 10% of the price of the lens.
It signifies that if you happen to shoot with a $1000 high quality lens, you’ll need to spend round $100 to match lens high quality.
I discover that the rule works fairly nicely for me. For instance, after I was trying to match my greatest lens Fujinon 10-24mm, with the protecting UV filter, I discovered just a few fashions with excessive mild transmission charges at round $90-100.
And if you happen to shoot with a $300-400 lens, the $40 Tiffen UV safety filter shall be ample.
